input-selector pixelation when changing active-pad

[jaime]

Hi,

I have two h264 encoded rtsp sources from IP cameras, and I want to switch
between cameras every 20 seconds, and save the output into a file.  The
problem I face is when switching, I'm expecting a fast switch but it does a
slow pixelated transition between the previous active pad frames and the new
one.

The pipeline looks like:

rtspsrc -> queue -> depay -> input selector -> h264parse -> flvmux ->
filesink

I tried all the input-selector property combinations; cache-buffers
(TRUE|FALSE), sync-streams (TRUE | FALSE), sync-mode (0|1) with no different
results

I also tried:

rtspsrc -> queue -> depay -> h264parse -> input selector -> flvmux ->
filesink

With no different results either.

The libraries Gstreamer 1.8.3 on Ubuntu 16.04 LTS

Could you please shed some light here?


With regards
